Like numerals refer to like parts throughout the several figures.

The cable 3,. which is connected with the drill pipe, is wound upon a drum 9 keyed to the shaft 10, (see Fig. 1). This drum 1s provided with the brake wheels 11 and 12 and i the brake bands 13, 14 controlled by the lever 15.

The drum is driven from the shaft 16 by ineans of a sprocket 17, belt 18 and sprocket 19 on the shaft 10; The shaft 16 is driven by belt 22 and the sprocket wheel 20.

The drum is driven at low speed through clutch members 23, 24 controlled by lever 23, sprocket wheels 17, 19 and belt 18 and at high speed by means of the sprocket wheel 25, belt 26, sprocket 27, and clutch members 29, 28, the latter being controlled by lever 28".

The drum is driven at an intermediate speed by sprocket wheel 30, belt 31 and sprocket wheel 32, the latter being connected to the shaft by clutch members 34 and 33. The drill pipe is rotated by means of sprocket wheel 8 connected to the shaft 16 by clutch members 36, 35, the latter being moved by lever 37, pivoted at 38, and connected by crank 41 to shaft 40 operated by handle 42.

. A sprocket wheel 44 is connected to shaft 10 by clutch members 33, 45. Clutch member 33 is actuated by lever 46 pivoted at 47 and connected to piece 48 which is connected with crank 49 on shaft 50 carrying hub 51 of .foot lever 52. Member 33' is moved to en-. gage member 45 by hand lever 53 pivoted at' 54 and connected with a sleeve 55 having a projection 56 working in aguide 57. Sleeve 55 has a beveled face 58 adapted to engage beveled face 59 on member 60 rotating with shaft 50. I

The clutch member 33, when released, is

In order that the frame-supporting the shafts 1.0 and 11 shall not be unduly extended because of the numerous sprocket wheels associated therewith, and particularly with centrally located by means of springs 61, 62. I

the shaft 10, I arrange the sprocket wheel 44 with a hub which projects into the bearing. This gives an extended hub for the sprocket wheel 44, without lengthening the frame.

This extended hub is necessary to hold the sprocket wheel in its proper position when it is connected with the pump The shafts 16 and 10 are mounted in bearings in a frame which frame is usually assembled in the field at the point of use. I

In the construction heretofore used, the frame has been made of wood and there has been great difficulty in getting the bearings in proper alignment so that the two shafts will be parallel as the tightening up of screws in wood tends to move the parts out of alignment.

The construction herein shown is arranged -always be in proper position.

shown, this is accompllshed by the top and to remedy this evil. The bearings for the shafts are located on the upright members 66, 67, and 68 of the frame. These members are made of metal, preferably of an I beam cross section as shown in Fig. 6 so as tov make them light but still strong and durable. Each member has two bearings preferably arranged on opposite .sides thereof, as shown in Fig. 2. This figure shows the central member 67. Integral with the member 67 is a bearing element 69 for the shaft 16 and a bearing element 70 for the shaft 10. These bearing elements are, therefore, in fixed positions with relation to each other. The shaft 16 is held in place by a removable cap 71 which is held in position by screws 72 and 7 3. The shaft 10 is held in place by a removable cap 74 held in position by screws 75 and 76. Since these screws work in threaded holes in the metal, there can be no drawing of the parts out of alignment when they are tightened.

The other members 66 and 68 are similarly constructed and ,have similar bearing elements. The parts thereof which show in Fig. 1 have applied thereto, similar reference numerals with the exponents a and b. Some means is rovided for properly aligning the several earings on the several members 66, 67 and 68, so that when the parts are assembled in the field, these bearings will As herein bottom aligning members 77 and 78. The top aligning member 77 is shown separately in Fig. 7 and the bottom aligning member 78 is'shown separately in Fl .4. These members may have ortions of t e metal omitted in i order to lig ten the construction. These members are also preferably cast and extend along the top and bottom of the members 66, 67 and 68 and are provided with projections where they are engaged by. the members 66, 67 and 68 which projections may be planed off in the shop so that the bearings on all of the members 66, 67, and 68 will be in proper alignment. As herein shown the aligning.

member 77'is provided with projections 79, 80 and 81 which may be finished or planed, as above set out. I prefer to provide the upper aligning member 77 with flanges 82, 83-and 84 which overlap the edges of the members 66, 67 and 68 as shown in Fi 2. The bottom aligning member 78 is provided with the projections 85, 86 and 87 which are planed off to secure the proper alignment of the shafts.- In assembling the parts, the aligning members 77 and 8 with the top and bottom beams 88and 89, by means of bolts 90, 91, the bolts 91 also passing through the members 66, 67 and 68. The ahgning'member 77 is connected with the members 66, 67, and 68 by the bolts 92 and the aligning member 78 is connected with the members 66, 67 and 68 by the bolts 93. The

are connected beams 88 and 89 are connected together by the rods 94 and 95. A floor for the operator i provide the top aligning member 77 with a projection 98 which overlaps its associated bearing member or post, the bearing member or post 68 being shown in Fig. 9. A removable fastening device 99 fastens the parts together.

The bottom aligning member 78 is provided with an inclined upper face 101 which is engaged by the portion 100 of the bearing member. The fastening device 98 shown in Fig. 2 is omitted and a removable fastening device 102 at the side used. The bolt 91 may be the same as in Fig. 2.

It will be seen that when the fastening devices 99, 102 and 91 and the cap 74 are removed, the hearing member may be rotated or rocked about the shaft 16 as shown in dotted lines in Fig. 9. It may then be removed by removing the cap 71. It will thus be seen that each of the posts or bear-in supports may be separately and indepen ently removed.

It will be seen that by means of this construction the parts maybe completely aligned and that when set up in the field com lete alignment of the bearings of the sha ts is assured. It will further be seen that the perfect alignment of the bearings of the shafts will not be affected in any way by the number of times the device is taken down and set up. This construction, therefore, provides a. strong, and durable draw works which can be easily taken down and moved from place to place and easily and quickly assembled at the point of use requiring no skilled Ine- 'chanics to secure and maintain the proper ali nment of the bearings.
